[nfbfkjvv] Reinforced blacktop

Pave with asphalt with a grid of metal embedded, but not for strength but heat distribution.

Application is: roadway or driveway partially covered in snow.  Sunlight hits the uncovered portion, heating it well because of its black color.  The heat gets transmitted through the embedded metal to the covered portions, melting the snow from underneath (and creating more uncovered portions, so beneficial positive feedback).
